AMP-310 600A AC TRMS Motor Maintenance HVAC Clamp Meter

Whether you need an amp clamp for HVAC, general electrical or motor testing applications, the AMP-310 Clamp Meter, with its large backlit display, has the features you need. HVAC technicians will find the temperature and capacitance measurements they need plus DC Microamps for testing flame sensors. It also had core motor testing capabilities such as motor rotation, 3-phase sequence testing, and inrush current measurement for motor start-up monitoring. The low pass filter allows you to accurately measure current and voltage on variable frequency drives. The Amp-Tip function allows for precise measurement of current down to the tenth of an Amp, enabling accurate current measurement of both large and small diameter wires. It also offers a full range of standard multimeter features, including AC current, AC/DC voltage, frequency, True-RMS, non-contact voltage detection, resistance, continuity and a CAT III 600 V safety rating.

Great MeterNought this meter about a year ago and love it. Use it daily and have had not trouble with accurate readings.

No inrush current and capacitance measurements are problematic.I paid about $150, but it just doesn't live up to expectations. Its an HVAC meter but capacitance readings are way off. Probably because of the 1.5v batteries, most good meters use 9v. Experimented and compared to readings from a Fluke 116 and an Amprobe ACDC 54nav, the capacitance readings with this meter were all over the place. This leaves doubt as to the reading it finally displays is correct?This meter won't/can't do inrush LRA current. But it does do three phase rotation and has a third lead to make this easy. It is a nice option but I have never had to use it before.
I would put this meter on below a UEI 379 [I also own one of these] which is less expensive and does capacitance real accurately.
I was not able to use or rely on this meter and returned it to Amazon. I found a well priced Amprobe ACD 51nav and so far I am very happy with it. I would recommend that meter, I can't recommend this one.

Great features.I've been using this meter for about two months. I am an industrial maintenance electrician. I bought it especially for the motor rotation checking feature and it works well. I also like that it reads frequency and amps on VFD drive outputs. It is also nice to have an extra temperature probe. I just bought the HVAC model because I already had an AC/DC amprobe good to 1000 amps.

Great size, excellent features.I've been using this meter for approximately 3 months now in a commercial/industrial HVAC setting.
I really like the size and feel of the clamp meter, It is ideal for service technician use as it doesn't weigh down your bag very much and takes up little space. I've tested the accuracy of the meter against my precision digital multimeter through a series of tests including AC/DC volts, resistance, temperature, capacitance and amperage. The AMP-310 performed very well and was exceptionally close in terms of accuracy.
The test lead wires are basic vinyl, the leads themselves have a really nice feel (silicone?) to them. Strain relief is ok, the alligator clips are well made and clamp on securely. It's great that they are included.
The over sized display is ideal, the backlight is adequate but it times out much too quickly. (only 30 seconds) Viewing angles are average.
I am a little critical of the storage/carrying case, it just doesn't fit the meter very well as it seems to be too wide. Almost as though it was made for a DMM and adapted to the AMP-310. It does have an internal pocket / strap and does hold all the accessories nicely. Just doesn't fit in my tool bag very well.
My favorite features of this meter are:
Selector switch is excellent, good feel, construction- probably the best I've used on a clamp meter. (I have had a number of meters over the years)
The amp tip on the clamp is really quite nice, offering high accuracy readings on single wires.
Display size is excellent
Least favorite features of the meter are:
Carrying case doesn't quite match the meter
Fast timeout of backlight
I trust this meter in the field and look forward to using it for many years.
